The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) IF: 1.1 To calculate the five year Impact Factor, citations are counted in 2017 to the previous five years and divided by the source items published in the previous five years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) 5-Year IF: 1.3 The Eigenfactor score, developed by Jevin West and Carl Bergstrom at the University of Washington, is a rating of the total importance of a scientific journal. Journals are rated according to the number of incoming citations, with citations from highly ranked journals weighted to make a larger contribution to the eigenfactor than those from poorly ranked journals. Eigenfactor: 0.0002 The Journal Citation Indicator (JCI) is a single measurement of the field-normalized citation impact of journals in the Web of Science Core Collection across disciplines. The key words here are that the metric is normalized and cross-disciplinary. JCI: 0.33 SJR: 0.256 SNIP: 0.49 CiteScore™:: 2.4 H-Index: 23

要約

Computational fluid dynamics based approach is used to investigate the momentum and mass transfer behaviors of swarms of contaminated bubbles in surfactant-laden power-law liquids using a segregated approach. Effects of surface contamination and bubble holdup are incorporated in the solver through spherical stagnant cap model and free surface cell model, respectively. Extensive new results are obtained on streamline and vorticity patterns, drag coefficients, concentration contours and local and surface averaged Sherwood numbers of contaminated bubbles in the range of conditions as: Reynolds number, Re = 1 to 200; Schmidt number, Sc = 1 to 100; bubble holdup, Φ = 0.1 to 0.5; stagnant cap angle, α = 0 to 180° and power-law behavior index, n = 0.6 to 1. Some of the key findings indicate that the drag coefficients decrease with the decreasing power-law index and/or with the decreasing cap angle and/or with the decreasing bubble holdup and/or with the increasing Reynolds number. The concentration boundary layer become thinner with the decreasing cap angle and/or with the decreasing power-law index regardless the values of the Reynolds and/or Schmidt numbers. The rate of mass transfer is found to increase with the decreasing cap angle and/or with the decreasing power-law index and/or with the increasing bubble holdup and/or with the increasing Reynolds and Schmidt numbers.
